1997 or somewhere around there. With the regular purple top it's pretty common and usually sell $75-100. I have one hanging in the garage as well. The white top sheet was probally a warantee replacement board. Might be worth more to someone trying to collect all the Jamie Lynn boards/colorways, but beyond that I have no idea.

Sounds right. I don't plan to sell mine, but it is pretty odd about the white top sheet...

The base graphic is from 1996/1997 but the board is from the previous year (you can tell by the ribbed top sheet), so my guess is that it was made by a Mervin employee for him/her self. You can always join the lib tech snowboard collectors group on Facebook and ask the guys there, there are a lot of ex employees there.
